In this paper RoboCup Mid-size Robot are the object of study from the two sides of the robot system and the system of multi-robot cooperation, the main research results are as follows: First, this paper reasearches the problom of the hardware and software architecture of Mid-size robots. According to the real-time requirements of the competition, the paper designs the mechanism of omni-direction wheels, which achieves a great improvement on the traditional mechanism of two wheels robot, and a more flexible response. This mechanism can adapt well to the increasingly rapid pace of the competition. In allusion to the mechanism of omni-direction wheels, this paper designs the electrical control system of three nodes in the bottom, which could communicate fast to the laptop with serial port and match the real-time requirements well. According to the problom of hitting power and speed of robot when shooting, this paper designes a motor-driven tongue-shaped spring shooting mechanism, which has a simple mechanical structure, smaller space in size and simple control circuit. This shooting mechanism meets the real-time requirements of the competition better.
